Small Business Invoice Follow-Up Workload Statistics 2026

An unpaid invoice creates two problems for a small business. The cash is missing, and someone must spend time finding out why. That work includes checking the aging report, sending reminders, answering questions, documenting promises, and deciding when to escalate.

Current data shows how quickly the queue can grow. In a January 2025 QuickBooks survey, 56% of US small businesses said they were owed money from unpaid invoices. Among those businesses, the average unpaid amount was $17,500. Xero's transaction data then showed that US small businesses waited 28.8 days on average to be paid in the first quarter of 2026.

This page treats survey responses, accounting-platform data, government estimates, and calculated examples as different types of evidence. Each source has limits, so the figures should guide workload planning rather than promise a result for one company.

Invoice follow-up statistics at a glance

More than half of surveyed US firms were waiting for invoice money

The 2025 QuickBooks Small Business Late Payments Report gives a useful view of the open-invoice burden. It found that 56% of respondents were owed money from unpaid invoices. The average balance among those firms was $17,500.

The aging results show that this was not limited to invoices a few days past due. QuickBooks reported that 47% of respondents had at least some invoices more than 30 days overdue. Nearly one in ten invoices fell into that aging group on average.

Those findings came from an online survey, not an audit of company ledgers. QuickBooks surveyed 2,487 US small businesses with 0 to 100 employees in January 2025. Respondents came from a paid Dynata panel and an active QuickBooks customer panel. The report says that 47% includes everyone who selected a value above zero for the share of invoices overdue by more than 30 days.

That method makes the result easy to interpret, but it also gives it a clear boundary. The survey measures what owners and decision makers reported. It does not measure the full US business population through tax or banking records.

Payment time and DSO answer different questions

Xero reported an average US payment time of 28.8 days in the first quarter of 2026. Invoices were paid 9.0 days late on average, up from 8.4 days in the prior quarter. The release draws on aggregated and anonymized data from more than 32,000 US businesses on Xero's platform.

Xero's figure is not the same as days sales outstanding. Payment time measures how long fully paid invoices took to clear. DSO estimates the number of sales days still held in accounts receivable at a point in time.

The common DSO formula is:

DSO = ending accounts receivable / credit sales during the period x days in the period

Suppose a business ends a 30-day month with $40,000 in receivables and recorded $60,000 in credit sales:

DSO = $40,000 / $60,000 x 30
    = 20 days

This is a calculated example, not a published benchmark. A rising DSO can show slower collection, but invoice mix and seasonality also move the result. Compare it with the company's payment terms and its own earlier periods.

The Xero Small Business Insights methodology explains why its payment-time measure differs. Xero uses invoices marked fully paid in the relevant month, excludes invoices paid more than a year after issue, weights invoice values, adjusts the sample toward the industry mix of each country, and seasonally adjusts the result. Unpaid invoices are absent from that metric. A badly aged open balance can therefore exist even when the reported time for completed payments looks stable.

The collection workload can consume two working weeks

The clearest public estimate of collection labor comes from UK government research. The Department for Business and Trade and the Office of the Small Business Commissioner commissioned London Economics to study late payments. YouGov and IFF Research surveyed 1,455 businesses between January 15 and February 7, 2025.

The report found that 22% of businesses used staff time to chase unpaid debtors. It estimated 133 million collection hours across the UK economy, or 86 hours a year for each business affected by late payment. That is almost eleven eight-hour workdays.

The 86-hour figure is an estimate for affected UK businesses. It is not a US benchmark, and it does not say how the hours were divided among owners, finance staff, or outside help. It does provide a concrete workload test. A company that spends two hours each week reviewing aging, writing reminders, making calls, and updating notes reaches 104 hours in a year.

The work rarely arrives as one clean block. It breaks the day into small pieces:

• Review the current aging list and confirm which invoices remain open.
• Check that the customer received the invoice and supporting documents.
• Send the next reminder under the company's collection policy.
• Record disputes, payment promises, and the next contact date.
• Match receipts and close paid items.
• Route disputed or high-risk accounts to the owner or finance lead.

Good virtual assistant data entry services can support the record updates and document checks. The business should keep credit decisions, settlement terms, legal notices, and account write-offs with an authorized manager.

Late payments reduce the cash available for ordinary operations

The Federal Reserve Banks' 2024 Report on Payments found that roughly four in five small firms faced a payment-related challenge. Its analysis used the 2023 Small Business Credit Survey. The report also notes that customer payments are the main source of cash available to small businesses.

Payment trouble was not uniform. The Federal Reserve found that professional services, real estate, and manufacturing firms were more likely to accept checks and report slow-paying customers as a challenge. Firms that collected through a third party more often cited time-consuming payments and settlement delays.

QuickBooks found a similar cash pattern in its US survey. Among businesses with a larger share of invoices more than 30 days overdue, 50% reported a cash-flow problem. The comparison group, which had fewer overdue invoices, reported the problem at 34%.

The survey also found more credit use among the group with heavier overdue exposure. These firms were more likely to report using loans, credit lines, and business credit cards during the prior year. Their average card balance was 17% of the credit limit, compared with 11% for firms with less overdue exposure.

These are associations. The survey does not prove that late invoices caused each financing choice. A weak sales period or a large expense could affect both payment experience and borrowing. Even with that limit, the figures show why an aging queue belongs in cash planning rather than in an ignored inbox folder.

Small firms can carry a larger relative cash burden

The UK government study estimated that 28% of businesses were affected by late payments during the study period. It defined an affected business as one that took at least one listed action, such as chasing debtors, using finance, or reducing headcount.

Among affected firms, the report estimated that late payments equaled 4.61% of annual turnover for micro businesses with zero to nine employees. The estimate fell to 1.47% for businesses with 10 to 49 employees and 0.79% for those with 50 to 249 employees.

The amounts moved in the opposite direction because larger firms have more revenue. Affected micro businesses had an estimated £9,214 in late payments on average. The average was £52,081 for affected small businesses and £193,635 for affected medium businesses.

These UK estimates should not be converted into a US dollar benchmark. Their useful lesson is about scale: the smallest firms can have less money outstanding but a larger share of revenue tied up. That is why a short invoice list can still deserve daily attention.

How to measure the follow-up workload

A business needs both money measures and work measures. An aging report alone does not show the labor used to collect it.

Track follow-up time for four weeks before changing the process. Include aging review, email, calls, document retrieval, dispute routing, and payment matching. Do not count accounting analysis or cash decisions as clerical follow-up.

A simple capacity estimate looks like this:

Monthly follow-up hours = overdue invoices x contacts per invoice x minutes per contact / 60

For 80 overdue invoices, two contacts each, and nine minutes per contact, the estimate is 24 hours a month. This example assumes every contact takes the same time. Actual work will vary, especially when an invoice has a dispute or missing purchase record.

Where support helps, and where authority should stay

Invoice follow-up has a repeatable administrative layer. A trained assistant can prepare the aging queue, check contact details, send approved reminders, attach supporting records, log customer responses, and schedule the next action. Managed virtual assistant services can also add coverage and supervision when the queue needs attention every day.

Some tasks need tighter authority. The owner or finance lead should set credit terms, approve payment plans, settle disputes, send legal demands, choose collection agencies, and write off balances. Access should match the task. A person who sends reminders does not need unrestricted bank access.

The handoff works best when every aging band has a written action. For example, the business can assign an automatic reminder before the due date, a personal check after seven days, manager review after 30 days, and a formal decision at 60 days. The timing should match the contract and applicable law.

Businesses comparing staffing options can review broader services after measuring the queue. The useful buying question is not how many emails an assistant can send. It is whether the support process lowers open-item age and follow-up time without giving away financial authority.

Frequently asked questions

How much time do small businesses spend chasing late invoices?

UK government research estimated 86 hours a year for each business affected by late payment. That equals almost eleven eight-hour workdays. The estimate covers UK businesses and should not be treated as a US average.

How many small businesses have overdue invoices?

QuickBooks found that 56% of 2,487 surveyed US small businesses were owed money from unpaid invoices. It also found that 47% had at least some invoices more than 30 days overdue.

What is the average invoice payment time for a US small business?

Xero reported that US small businesses waited 28.8 days on average in the first quarter of 2026. Paid invoices arrived 9.0 days after their due dates on average. Xero bases these figures on completed invoice payments from its platform.

Is invoice payment time the same as DSO?

No. Invoice payment time measures how long paid invoices took to clear. DSO uses accounts receivable and credit sales to estimate how many sales days remain uncollected.

Which invoice follow-up tasks can an assistant handle?

An assistant can maintain the aging list, send approved reminders, find supporting documents, log responses, and schedule the next contact. A manager should retain authority over credit, settlements, legal action, write-offs, and bank access.
